As a Windows systems administrator with years of experience managing enterprise video conferencing setups, I've helped countless teams standardize Zoom settings for consistent meeting experiences. Here's how to force users into portrait view using proven Group Policy or Registry methods.
To enforce portrait view via Group Policy:
This locks users into portrait mode. To allow switching, set it to Disabled.
For finer control or non-Pro editions, use the Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies.


To re-enable switching, set the value to 0 or delete the DWORD. Restart applies changes reliably.
Gallery view requires more than two participants; otherwise, it's unavailable. Click the gallery button in the top-right corner during a call to toggle views when eligible.
Use Zoom's built-in options for personal use. To enforce it organization-wide, follow the Group Policy or Registry steps above—select Enabled or set DWORD to 1.
These methods ensure compliance across your Windows fleet. Questions? Test in a pilot group first.
